I'd like to see tinkers get extra shops. Right now, everyone can buy almost everything they want almost all the time if they're bringing 50 gold along and you're probably getting your best goodies from preparations anyway.
Tinkers also transmute items at their reduced rate. No clue if that's a bug or a feature, but it's certainly weird flavor-wise.
GG remains my favorite deity from every perspective, largely because of how harsh he is. He's still extremely powerful, and having your early-game decisions come back to haunt you if you're careless is my idea of fun. Even just nabbing humility and getting out of there is a major bonus without any risk. It actually bugs me when I get him and binlor (who's close to broken) and don't have to worry about his punishments.
